THE CRETACEOUS ROCKS OF BRITAIN. 
complete, and probably no two observers would divide the beds in 
exactly the same way, but in 1891 the succession was noted by me 
as follows: —

Grey sandy and marly chalk - - - - 4\ 
Firm marly chalk with grains of quartz and glau¬ 
conite. In one part this was shaly at the base, 
but it passes into the next - - - - 2j 
Very sandy glauconitic marl or marly sandstone, 
drying to a light greenish-grey (many fossils. 
— Am. [ Schloenb .] varians, and Stauronema 
Carteri) - .4 
Rough glauconitic sandstone, darker in tint (for 
details see Vol. I., p. 160) - 4 
Soft greenish sandstone, with few fossils - - 6

Lithologically, one would put the base of the Chalk at the bottom 
of No. 3, but the bed below still has much marly or chalky matter 
in the matrix, and contains the usual characteristic fossils of the 
Chloritic Marl, so that paleontologically it must be included in 
the Chalk. There is no break between 4 and 5, and it is possible 
that even the latter should be excluded from the Selbornian, for it 
contains Am. Mantelli and Turrilites Bechei. 
This quarry has yielded many fossils, and the following were 
collected here by myself and Mr. Rhodes from the beds numbered 
1, 2, 3, 4.
